The present invention relates to machinesfor making envelopes from envelope blanks and more particularly to an improved Scoring roll for use therein. Among the objects to be attained maybe mentioned an improved arrangement of the blades for producing thel longitudinal and transverse scoring lines in the blanks, im- A proved means for holding same so as to insure increased accuracy and ease of'adjustment as well as to facilitate the removal and replaceA ment of the parts, and improved guidemeans for the blanks for preventing them from adhei-ing to the scoring rolls'. V Y Other objects and advantages of my invention will be apparent as the description proceeds and the specific features of novelty.

will be point-ed out in the appended claims. M The invention will be bestunderstoodr by lreference to the following detailed description taken with the accompanying drawings, in which: 4 i Y' Y Fig. 1 is aview in front elevation of` an illustrative embodiment, parts being lin section and broken away; f 'Y v Fig. 2 is a detail of the spacer plate used and showing the manner, ofits attachment to the shaft; Y p Fig. 3 is a view on a reduced Scale of the l main shaft and showing a retaining groove in the same;

Fig. 4 is a view of the middle portion of'r the hbl der for the long transverse blades; Fig. 5 is a view of oneof aset'iof blades comprising a second scoring element;

Figs. 6, 7, 8 and 9 are views taken respectively along the lines 6 6, 7-7, 8-8, and 9-9 of Fig. 1;

Fig. 10 is a view in section through the' spacer' element; and y y Fig. 111s a diagrammatic showing of a plane development ofthe scoring blades and also of the blank to be scored.

The general arrangement of the y scoring blades inthe preferred embodiment is illus-'- trat-ed in Figure 11. Advantage is here taken of the fact thatin an envelope blank of the type operated upon, the score lines intersecton the periphery of the blank whereby the position to abut transverse blade 16. The

5U' scoring blades may extend beyond the points of intersection of the score lines. As will be evident from Fig. 11, one of the transverse scoring blades extends ythe length of the longest score line for which the machine is adapted, while abutting this blade is a, pair of circumferential blades which between them contain the second transverse blade which is of adjustable length.

The mechanisn'iv for carrying 'out this a'r-r rangement may now be described in detail.

Referring to Fig. 1, 10 denotes Vthe shaft' upon which` the various elements are mounted, including a pair ofcollars 11, 12, between which the scoring blades are mounted; as a will be bestseen from Fig. 9, collar12, for example, is splint and has adjacent portions held together by means of a set screw 12a by means of which the collar is firmly aiiixed to the shaft, thesame construction obtaining in the Vcase of collar 11. Collars 1l and 12 have attached thereto a transverse bar 14 of segmental shape and secured to saidV collars by means of screws 1li-a, 14-6, one purpose ofv such bar being to Lconstitute a feeding sector for the scoring roll. Attached to lsaid feeding segment 14 is a pair of transverse scoring bladesl, 16 which together extend the length of the scoringrroll. As will be'seen from Fig. '1,each blade 16 abuts a pin 19 at thev middlev ofy bar 14, the purpose of which is to insure an exact spacing between said blades in order to accommodate the blank guiding member'A, to be referred to.here' after. Bar 14 also has a circumferential Vslot 17 to accommodate guide member A. Each blade 16 is secured to said feeding sector 14 yby means of bolts 20, 2O and 21,21, Fig. 1.V By lmeans of theL .elementsy thus far recited,

the long `transverse scoring blades 16 arek mounted upon theshaft 10. l i

Also adjust-ably mounted on shaft 10 are the circumferential scoring jblades' 22,` '23,

yblade 22, for example, being-mounted upon a collar24 by'means ofy retaining-screws'25,

25,25, collar 24 beingl split and securedV to 4shaft l0 by means of a set screw 27. In this manner blade 22, `for example, is adjustable angularly of the shaft and is, at all'times in thereto.

same construct-ion applies to circumferential blade 23.

The second transverse blade 30 is composed preferably of three elements, 30-a, 30e-b, vand 30.c, Figsl, 9, and 11, the arrangement ,being such that the straight edges of the blades are together whereby Va scoringfblade is formed' either by thecombination of two blades or by a single blade, reference being had to Figs. 6 to 9inclusive. Blades 30-a, 30-Z ,30'0 are adjustably held in holder members 32 by means of set screws 33, Fig. 1. I also find it desirable .to fix theholder'members 32 angularly with respect to theshaft 10 by mounting same in a groove 35, Figs. 8 and l1, havingvits sides diverging inwardly, `and in'which a key'36 is mounted, and a screw 37 attached thereto. In this `manner holder members 32 are adjustable longitudinally of the shaft 10 but cannot rotate with respect Also, by loosening set screws 33 the blades 30 are extensible as desired so as always to abut the circumferential blades 22, 23. Said blades are also provided with a slot 34 to accommodate the guide A. lS/Ieans .for insuring the Vregistry ofsaid slots and guide will be described below.

In the foregoing I have described the Vmountingof the pairs of transverse and circumferential scoring blades whlch upon .planeY development enclose a rectangle as seen in F igjIl. I nd it desirable -to provide a spacer member 40l in the space enclosed by said blades in' orderk to `prevent the blanks from being caught therein, said member 40 being illustrated in Figs. 2 and 10 and `comprising a split ring 41 held together by means of a set screw 42 threaded into enlargements 43 in said ring. Member 40 also Vcomprises a lin or rib-45, Figs. 10 and 1, which is useful.

in serving as a` means for locating the external slot34 of blade 30 -c in correct position-owing to the fact that'said rib registers with a slot 30-aa in the inner edge of said blade e, which is directly in line with slot 34. Spacer member 40 itself is located on the shaft 10 by vmeans of studs 46,47, Fig. 2, secured to said shaft. I nd it desirable to have the external face of the lspacer member resiliently mounted, such face plate 48, Figs. 2 and 10, being held against lips 49 of said member by means of springs 52, 53, screws 5G and 51 serving-as guides for said plate. Also said spacer member 40 is Apreferably fixed to shaft 10 by means of a key-55 in a groove 56 in said shaft whereby, the spacer member cannot rotate with reference to the shaft.

Cooperating with the scoring roll thus far described is a counter roller 60 having thereon a resilient outer. layer 61 against which the scoring blades adhere. 'Io further insure the accurate disposition of the transverse counter roller as by adhering to the scoring blades. To accomplish this I provide a guide member A disposed preferably so as to be abovethe median line of the envelope blank and which passes entirely .through the roll pair comprising the scoring roll and the counter roll 60, it being noted that transverse blades30, spacer member 40, transverse member 14 all containing a circumferential slot to accommodate `this guide. Also provided adjacent to said rolls is a table 65 having portions which terminate close to roll 60 and which effectively prevent the blank from adhering to said roll.` Guide A is supported from above the table 65 by means not shown.

Itwill be evident that by the means described in the foregoing, the envelope blanks may be quickly and' correctly scored, and furthermore, without danger that the blanks be carried out of their course Vin the machine by adhering to either the ,scoring roll or the counter roll thereof. Furthermore,it will be evident that easy and positive means are provided for adjusting the blades for different sizes of blanks. f

I wish it understood that various changes may be lmade in the specific embodiment described without departing from the spirit of the invention, and that parts thereof may be used without others.
